| Abstract: | The medical and chemical wastewater was a high concentration and intractable organic wastewater. The last effluent was directly influenced by the pretreatment. The micro - electrolysis and SBR bioreactor were used to remove nitrobenzene wastewater. The results showed that the removal efficiency of nitrobenzene and COD by the micro - electrolysis could reach 93 % and 45 % or so respectively, which were affected by pH and HRT. The ratio of BOD5/CODCr was increased from 0.24 to 0.55. The process could improve biodegradability of the wastewater. Running cost of this treating technology was 2.52 yuan/m^3 . |
